Hydrocarbon pyrolysis This is the only method that does notproduce carbon dioxide providing the material is decomposed at high enough temperatures in the absence of oxygen. Hydrocarbon pyrolysis This is the only method that does not produce carbon dioxide providing the material is decomposed at high enough temperatures in the absence of oxygen. Process chemistry for methane: CH 4 C +2H 2 [ΔH=75.6 kJ/mol] In addition to hydrogen as a major product, the process produces a very important by-product – clean carbon.

Conclusions The primary experimental investigation and kinetics simulation of the methane autothermal reforming were performed. The aim of research was to determine optimal process condition for autothermal reforming in order to get maximum H 2 concentration in the product gas mixture. Gathered information shows, that the H 2 yield increases with decreasing of the air excess ratio and the optimal temperature range in the reactor is 1200 – 1400 o C. The most part of hydrogen (70 – 90%) occurs in the primary reaction zone where the fast exothermal partial oxidation (POX) reaction take place. The remain hydrogen produced in the slow conversion zone where the endothermic water-gas shift reaction occurs.
